After the 50 outer plates can be easily completed, it is reported that it is difficult to weld the inner core reinforcement column 64 of the inner member and the 54 inner core column overlap each other. It is shown that the inside and the inside overlap each other at a certain position; except that the door 65 overlaps with a certain plate 50 as shown in FIG. 7C, it can be easily welded and difficult to weld to the outer plate 50 and the center strong column 54 and the top side rail 55 each other. The upper and lower rear 51 and the wheel extension 5 3 shown in the top side are separated from the side plate 50. Therefore, at point P5, if the work efficiency and other factors are considered, the actual welding is performed; The parts are connected to each other as shown in Figure 7A. The pillars 64 are superimposed on each other. The reinforced door 55 and the P6 are not as strong as the above. The parts that cannot be welded actually have lower strength. In particular, there is no welding as shown in Figure 7C. The side reinforcement door Jian 65 and the wheel arch extension 53 will unduly reduce the intensity of resistance to deviation collisions. Therefore, the exemplary object of the present invention is to weld the portions corresponding to the side reinforced doors and the wheel arch extensions, so as to increase the strength against deviation collisions. To achieve the above object, according to the present invention, a manufacturing method for manufacturing a side panel of a vehicle body is provided, in which a plurality of inner panels are installed in an outer panel including a front opening.
